80611

The Chroma 80611 is a timing and noise analyzer module designed for use in Chroma's automated test systems (ATS) for power supply testing. The 80611 can be populated with up to ten noise cards, each with a 20 MHz bandwidth. The module provides ten channels for DC voltage input to measure timing and noise parameters.^[3][2][1]

The Chroma 80611 provides auxiliary controls including eight pairs of built-in relays and 16-bit TTL input/output signals. The module includes six external trigger sources that create a total of 24 different triggering options. For high-bandwidth applications the 80611 can be configured with up to two 10-input by 2-output, 100 MHz high-frequency multiplexer cards to route signals to an oscilloscope.^[2][4]

The Chroma 80611 Timing and Noise Analyzer is a module that installs into a Chroma C8000 or Power Pro III automated test system. The module is controlled exclusively by the Chroma ATS test program through a GPIB bus; there is no keypad or general GPIB command control. The 80611 accepts up to ten DC voltage input channels routed through user-selectable multiplexers that can also pass signals to an external digital voltmeter or oscilloscope.^[2][1]

Each noise card installed in the 80611 provides parallel and differential measurements of voltage parameters including peak-to-peak, RMS, overshoot, undershoot, turn-on time, turn-off time, rise time, and fall time. The 80611N noise card has a bandwidth of up to 400 kHz for dynamic voltage peak measurements and a noise specification bandwidth of 6 Hz to 20 MHz. The mainframe provides a 10 x 4 low-frequency multiplexer for routing signals to the system DMM or scope.^[2]

The Chroma 80611 is applied in automated test systems for high-speed switching power supply testing. The module is suited for testing multiple-output power supplies by providing parallel timing and noise measurements. The 80611 is also used in systems designed for testing LED power drivers, adapters, and battery chargers.^[2][1]
